A marathoner can run for as long as desired, without needing to make Fort saves to continue running.

ECOLOGY

Environment any underground and cold forestsOrganization usually solitaryTreasure incidental

Marathoners are octopedal, vaguely saurian predators. Their skull is entirely a maw. The creatures have no eyes, and perceive the world from swollen sensory-glands on each haunch. Marathoners lack nostrils and have only the most rudimentary sense of smell or taste. They mistrust carrion, and only eat fresh kills.

Twitchy and hyper-aggressive, marathoners are in almost constant motion. Snapping their powerful jaws, scratching and biting, snarling their warbling snarls, they seem to be constantly spoiling for a kill. The beasts make an ideal guard animal for the paranoid and the wealthy. A kennel of the fierce lizards is a standard precaution at many estates and manors, woe be to anyone who jumps the wall.

Marathoners are uniformly feared not only because of their raw aggression, but because they are among the most tireless example of a pure pursuit hunter in the Multiverse.

The creatures are capable of running without sleep or rest for several days at a time and are capable of chasing horses to death. On high tech worlds, marathoners can chase an automobile or truck until its tank hits empty, then slaughter the driver.
